The Aspire Pockex Coils for the PockeX AIO Vape make use of their innovative U-Tech Coil Technology by diverting the flow of air inside the coil head causing it to pass the coil twice before making its way to your unsuspecting taste buds. The result of this double-pass is superbly dense vapor and unparalleled flavor in its class. At a recommended operational range of 18 to 23 watts, these Aspire Pocket X Coils, made of SS316L, are particularly mouth-to-lung-friendly; providing a cool, familiar, flavor-focused draw for the beginner, expert, and everyone in between. They are also compatible with the Aspire Nautilus X tank if you're looking for some lower ohms to go with your Nautilus.
